Introduction to Win11 wireless network card driver
802.11nwlan wireless network card driver is a wireless transmission standard protocol behind 802.11a/b/g. In order to achieve high-bandwidth and high-quality WLAN services and enable wireless LAN to reach the performance level of Ethernet, 802.11 Task Group n (tgn) came into being. The 802.11n standard was not officially approved by the IEEE until 2009, but the mimo There are many manufacturers of OFDM technology, including D-link, Airgo, Bermai, Broadcom, Agere Systems, Atheros, Cisco, Intel, etc. The products include wireless network cards, wireless routers, etc., and have been widely used in PCs and laptops.

802.11n mainly combines the optimization of the physical layer and mac layer to fully improve the throughput of WLAN technology.
The main physical layer technologies involve mimo, mimo-ofdm, 40mhz, short gi and other technologies, thereby increasing the physical layer throughput to 600mbps.
If you only increase the rate of the physical layer without optimizing the mac protocol layer such as air interface access, the physical layer optimization of 802.11n will not be able to play its role. Just like even if a very wide road is built, if the dispatching and management of traffic flow cannot keep up, congestion and inefficiency will still occur. Therefore, 802.11n uses block confirmation, frame aggregation and other technologies for mac, which greatly improves the efficiency of mac layer.
In terms of compatibility, 802.11n uses a software radio technology, which is a fully programmable hardware platform, so that base stations and terminals of different systems can achieve interoperability and compatibility through different software on this platform, which greatly improves the compatibility of wlan. This means that WLAN will not only achieve 802.11n forward and backward compatibility, but also achieve the combination of WLAN and wireless wide area networks, such as 3G.
In terms of transmission rate, 802.11n can increase the transmission rate of wlan from the 54mbps currently provided by 802.11a and 802.11g to 300mbps or even as high as 600mbps. Mimo is applied thanks to the combination of mimo (multiple input, multiple output) and ofdm (orthogonal frequency division multiplexing) technology. OFDM technology improves the quality of wireless transmission and greatly increases the transmission rate.
In terms of coverage, 802.11n uses smart antenna technology. Through an antenna array composed of multiple independent antennas, the beam can be dynamically adjusted to ensure that WLAN users receive stable signals and reduce interference from other signals. Therefore, its coverage can be expanded to several square kilometers, greatly improving WLAN mobility.
